    to back flush your ro filter remove the wast water line from the ro filter and remove the restricter and then hook it back up turn the water on and let it run for about 2 minutes then put the restricter back in and then you should be good

    You could also set up a bypass with Y-couplings and a ball valve.
    Set it up so it would bypass the flow restrictor.
    Close the ball valve to allow normal operation, and open it to allow the water to bypass the flow restrictor. This would allow you to flush the surface of the membrane without having to disconnect any tubes.
